There's one major problem with apps of any sort of scale that involve any scenario where dangerous accidents are possible. The problem is that as these apps scale, these accidents will happen, and with a degree of regularity that also scales alongside the growth of the app/company - even when there is absolutely 0 negligence involved. And the media then takes these anecdotal bits and implies they are representative of the service itself, further implying negligence.
In this case the article mentions that the driver was an actively licensed taxi/vocational driver that had been driving taxis on and off for 40+ years. And had completed more than 500 flawless rides on Grab in his month of work with them, with a good overall review rating. The only thing the author mentions as something trying to be framed as a red flag is that in his decades of driving, the driver states he had "several small and big road accidents."
Let's look into that. This [1] article from the NYTimes indicates that taxis get into crashes about 4.6 times per million miles driven, which was substantially better than the rate for non-taxi drivers. Another search indicated that taxi drivers hit around 70k miles per year. [2] So we now have the numbers we need. 1 million / 70k / 4.6 = 1 crash per 3.1 years. That means a perfectly average taxi driver gets into a crash every 3.1 years of driving on average. A taxi driver that's been driving for 40 years would expect to get into an average of about 13 crashes. Given that the article mentions our driver drove taxis "on and off", his accounting of "several" means he was probably just about perfectly average.
The point of this is that anecdotal evidence is irrelevant. I suppose like the old saying goes, Dog bites man is not news. Man bites dog is news. Yet when all you see from media is reporting these incidents of man bites dog, it leads to a distorted worldview where there seems to be a rash of men biting dogs.
